航天发动机多余物自动检测系统

An Automatic Loose Particle Detection System for Aerospace Engines

针对现有多余物检测装置检测效率低、精度低等问题,研制了一种航天发动机多余物自动检测系统,系统包括电机驱动转台的机械装置、驱动控制电路和信号调理采集电路。本文采用阈值比较和累积平均能量比较方法,实现多余物的粒径识别和空间定位。

Aimed at the shortcomings of conventional loose particle detection systems such as low efficiency and low precision, an automatic loose particle detection system for aerospace engines was de-veloped. It was composed of swivel stand driven by motor, driver control circuit, data conditioning and acquisition circuit. With the algorithms of threshold comparison and accumulated average energy compari-son, the computer gives results of particle size and location.
